In this heart-pounding documentary—a classic Western, set in the 21st century—vigilantes on both sides of the U.S.-Mexico border are pitted against the vicious Mexican drug cartels. With unprecedented access, Vineyard resident and MVFF alum Matthew Heineman embeds himself among the rebels as each side vies to bring its own brand of justice to a society in which institutions have failed. This chilling journalistic achievement provokes deep questions about lawlessness, the breakdown of order, and whether it is just for citizens to fight violence with violence.
